That being said, if you don’t use Apple products (or only one apple product), they are not really more convenient then any other headphones.
Not having an iPad, I always got by with having a single set of earphones plugged in my work machine, and bluetooth ones for my phone, which I use for running.
I can imagine having many more devices and using the same set for all could be preferable.
Have you ever needed to be on a phone call after you took the call on the phone, but would like to switch headset, but because Bluetooth still sucks it doesn't even show the headset in the list, so you have to power down the headset, restart in pairing mode...
Yeah, I've done that plenty of times using a Bluetooth headset. You will never do that using an iPhone and AirPods. You'll just push the button, and it will switch without drama. And it will work that way tomorrow, too. That's why I've paid eye-watering sums for headsets with W1/H1 chips in them.
Also, isn't the point of a bluetooth handset that you can make the call there?
